Cayman/Boxster S, Cayman R, Boxster Spyder Data Monitors

This ECU has all of the different monitors grouped into different blocks, many of which are members of more than one block.  When looking at data, when the computer looks at a block, whether one or all of them are selected will not impact the logging speed however, as you look at more than one block it may impact the logging speed as a whole.  A good practice would be to pick as many of your desired monitors from the same group as possible, as this will allow the monitoring speed to be as high as possible.

• (G01) Ambient Pressure-DME
  • This value is measured by the ambient pressure sensor in the DME control unit and is used to calculate the altitude correction factor. The altitude correction factor is used to inhibit secondary air, tank vent valve and fuel tank leakage diagnosis. If the mass air flow sensor (MAF) fails, a substitute value for the air mass is formed from the engine speed, throttle position and altitude correction factor. The measuring range is from 400 mbar to 1200 mbar.

Cayman/Boxster S, Cayman R, Boxster Spyder Data Monitors

• (G01) Coolant Temp
  • The coolant temperature is calculated from the voltage signal of the engine temperature sensor and is used to correct the DME maps in accordance with the temperature. The temperature is passed on to the gateway control unit via CAN. It is also used as the basis for thermostat diagnosis. (The warm-up phase is monitored using a temperature model.) If there is no signal, a substitute value is formed in the DME control unit and is then displayed here.

• (G01) Fuel Pressure
